arm64: Mandate VMAP_STACK 



On arm64, VMAP_STACK has been enabled by default for a while now, and
the only reason to disable it was a historical lack of support for
KASAN_VMALLOC. Today there's no good reason to disable VMAP_STACK.

Mandate VMAP_STACK, which will allow code to be simplified in
subsequent patches.
